3 1. Nursing Workload: Acuity & ALOS Patient acuity increased on medical and surgical units ALOS across all 80 hospitals decreased from 78.3 to 77.6 hours across all case types Concentrating nursing care into a shorter period 5 1. Patient Movements & Case Types Patient movements increased from an average of 2.10 units/wards per patient per episode to 2.26 The average number of patients per bed per day was 1.25 The average number of case types (DRGs) per nursing unit per year increased 6 3

4 1. Nursing Hours Per Patient Day Nursing hours/patient day (NHPPD) were highly variable Mean 5.1 Range On average approximately one additional hour of care per day, above that provided, was needed for each patient 7 1. Nurse: Patient Ratios All nursing staff AM Mean 3.8 ( ) PM Mean 4.5 (1.8 12) Night Mean 8.2 (3.3 19) RN staff only AM Mean 5.7 ( ) PM Mean 6.6 ( ) Night Mean 11.8 (3.7 36) Nurses caring for > 8 patients vs < 4 results in a 30% increased chance of dying Their capacity to provide surveillance decreases as patient numbers increase (Aiken et al. 2003) 8 4

5 2. Skill Mix & Staffing Trends Increased RNs in specialised units ED, ICU Medical, surgical & general units Maintained the same proportion of RN hours to patient hours BUT patient movements and acuity have increased on those units % RN Hours per Ward Wards 9 3. Patient Outcomes OPSN Decubitus ulcers, gastrointestinal bleeding, sepsis, shock, physiologic/metabolic derangement, pulmonary failure and failure to rescue» (Needleman et al., 2001; 2002) Falls Medication errors 10 5

6 3. Patient Outcomes A higher proportion of RNs resulted in decreased rates of: Decubitusulcers, gastrointestinal bleeding, sepsis, shock, physiologic/metabolic derangement, pulmonary failure and failure to rescue Fewer falls Fewer medication errors when: The proportion of planned admissions increased The proportion of nurses working on their usual ward increased A clinical nurse educator was present on the ward Decreased adverse events (falls, medication errors, pneumonia) with: Specialist nursing support (CNCs) A clinical nurse educator on the ward More hours of housekeeping The Work Environment Nursing work index (NWI-R) Autonomy Freedom to make important patient care and work decisions Control over practice Adequate support services allow me to spend time with my patients Nurse-doctor relationships Collaboration between nurses and physicians Resource adequacy Enough registered nurses on staff to provide quality patient care Leadership A nurse manager or immediate supervisor who is a good manager and leader» (Aiken & Patrician, 2000) Environmental Complexity Scale Unexpected changes in acuity Resequencing of work Nurse Demographics & Experience Job Satisfaction Violence 12 6

7 4. Satisfaction with the Job and Nursing Most nurses (67%) were satisfied with their current position and were not intending to leave Even more (72%) were satisfied with their chosen profession Higher levels of nurses satisfaction with the profession were linked to increased nurse autonomy and better relationships with doctors RNs were less satisfied with nursing than all other categories of nurse Violence & Abuse During the last five shifts: More than one-third of nurses reported experiencing recent emotional abuse and about 1 in 5 nurses reported threats of physical harm More than one in 10 reported actual physical abuse The source of violence was nearly exclusively patients and families Patient outcomes: Patients were more likely to experience a medication error or other adverse outcomes where nurses experience physical violence or threat of violence 14 7

8 4. Tasks Delayed Nurses reported an average of 1.4 tasks delayed and 1.7 not done per nurse per shift Tasks delayed or not done were statistically linked to Increased unanticipated changes in patient acuity Decreased resource adequacy (NWI-R) Decreased specialist nursing support (CNSs) Patient outcomes: Nurses delaying the completion of tasks linked to increased rates of adverse events Nursing Leadership Good nursing leadership was linked to: Job satisfaction Satisfaction with nursing Nurses who experienced good leadership on the ward: Were less likely to intend to leave their current job 16 8

9 4. Ward Stability Adverse patient outcomes increased as ward environments became less stable Fewer permanent staff Fewer nursing hours per patient day Decreased perception of nurse leadership No nurse educator support More patients per bed Higher levels of perception of violence 17 In Summary Skill mix (the proportion of RNs) is more critical to patient outcomes than hours of nursing provided Stability of the ward environment improves patient outcomes Good nursing leadership enhances the work environment 18 9

10 My discovery, as a patient first on a medical service and later in surgery, is that the institution is held together, glued together, enabled to function as an organism, by the nurses and by nobody else Lewis Thomas, MD, The Youngest Science, (1983 p.67) 19 Publications from this Research Duffield, C.
